Letters Paten-t No. 106,831, dated August 30, 1870.

IMPROVEMENT IN rANNrNe-Mr'nns.

The Schedule referred to in these Letters Patent andV making part of the same .'Z'o all whmn it may concern 'Be it known that I, DANIEL KANE, of Tivoli, in thecounty of Dubuque and State of Iowa, have invented a new and improved Fanning-Mill and I do hereby'declare that th'e following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification, in which- Figure l is an elevation of one side of my improved machine.

Figure 2 is a section taken longitudinally and in a vertical plane through the center of thenlachine.

Similar letters of reference indicate corresponding` parts in the two figures.

This invent-ion has for its object the improvement of machinery for winnowing grain. It consists in' the arrangement of two shoes or grain-guideson opposite sides ofva single fan, in such manner that the grain from the hopper will ilow through the machine in two separate streams, both of which will be subjected alike to blasts of air from said fan, as will be hereinafter explained.

To enable others skilled in the art to understand myinvention, I will explain its construct-ion and'op- In the accompanying drawing- A represents the frame of the improved machine, which may be of' any suitable length, breadth, and height, and which is adapted for receiving centrally within it a blast-f`an, F, which is supplied with air 0, made through the side housing boards.

- The fan-shaft f has its end bearings in boxes, which are supported on horizontal.cross-bars of the frame A, and this shaft is `rotated rapidly by gearing or otherwise.

Above the fau F, one or two hoppers, H, with adjustable bot-toms, J, are arranged, and below the hopper or hoppers are inclined planes, (l d, inclining from a point which is arranged in a vert-ical plane inl tersccting the axial plane of thefan-shaft f, for the purpose of dividing the stream or streams of grain flowing from the hopper or hoppers, and directing the 'grain downward and outward into two shoes, S S.

These shoes S S may be constructed in any manner common to wiunowing-machine slices, or in any other 4 suitable manner.

Each shoe, S, is hung by laterally-swinging brackets, h, and its inclined plane d has a loose support in a cross-beam arranged above the fan.

Each shoe receives a laterally shaking motion from a crank, C, on fan-shaft` f, by means ci' a pitman, lr, which is connected to said crank, and also to one ot the laterally-swinging bracket h.

Below the fau are two inclined converging spouts, g g, arra/nged so as'to receive the grain as it leaves both ofthe shoes S S, and deliver the grain into a receptacle placed beneath `the contiguous ends.

Between the spouts gg and the fan is a concave plate or board, on, which forms the floor of the fancase. The roof of this case is formed by the inclined planes d d ofthe shoes S S, as shown in iig. 2.

From the above description it will be seen that I adapt a single fan to act upon grain as it ows through two shoes arranged on opposite sides of the said fan;

also that the grain, ilowing in two streams from saidv slices, can be collected 'at the lower termini of two spouts into a singlevessel.

What I claim as my improvement in tanning-mills, and wish to secure by Letters Patent, is-

- The arrangement of the hopper H. H, fan-case al d on, fau F, shoes S S, anddischarging-guides g,- all constructed snbstantiallyas described, in the manner and for the purpose specified.
